Dominator Exhaust on a Yamaha XT660Z

- This is a layman's sound test of the Dominator exhaust installed on Yamaha XT660Z. The main reason to change the exhaust was to reduce the weight by almost 5 kg from the stock exhaust to the Dominator exhaust. The sound was tested without db killer and with two different db killers, medium and hard db killers. Further a catalytic converter was installed in the dominator exhaust pipe.

I love this bike but unfortunately it isn't available in America and that is pissing me off. I loved the sound with the hard DB killer because of the deep bass tone to it. Enjoy it sir.
Thank you.
Greetings. I fitted the same on my tenere... but i have no after market catalytic converter like yours. There is no restrictions in south Africa...yet, lol... but have you notice when the DB killer is in there is way more power through the rev range...with the DB killer completely removed, the power is noticeably less... i think it needs a bit of back compresion cause of the cat in the standard exhaust... i love the sound without the dB killer ...but want the power like the db killer inserted. Any advice?? Thanks for your video. Much appreciated
Thank you for the comment. I unfortunately do not have the knowledge to give you a qualified answer, but if someone reading this can help, please give your comment...
Please, is your db kyller is the medium or hard?
@@paulorafaelsacchettojr.1281 Sorry for the late answer. I use the hard db killer.
Hi, i have a MT-03 with the same engine.
When you change the exhaust, is it needed to change the settings of the fuel injection or not ?
I have just ended a 10,000 km round trip ranging from sea level to over 2000 m height with the stock settings and the hard db killer in the exhaust with no problem. I do not believe it is necessary to change the settings and actually felt that there was slightly more power at the bottom rpm.
You should only need to change that if you are adding stage 1 or 2 air filters - the exhaust change wont change a thing about how your engine is running. If you are changing the air filters then i suggest buying the Kev fuel mod from Aus. Takes a while for delivery but well worth the £130
You can buy the components for 10€ and build it yourself. No need to order such basic stuff from edge of the world with huge price tag. You will find the parts needed by googling “Tenere mod book.”
Hi! Probably a bit too late for this but where can you find the maximum allowed sound level for your bike? I put this exact exhaust on my bike and was paranoid at how loud the it sounded for other people
I think it depends on which country you are in, but in DK the noise limit was 90 DB measured at a certain drive by distance for my bike. As I recall the distance is around 7 meters. I think the best is to ask e.g. Yamaha in your country. They might know.
@@mcbluestreak5607 will do, thanks!
@@sowfistikated4521 you will find max. sound level for your bike on your bike itself. it is usually writtent on main frame, location: between the triple clamps (front forks holders). There is also your bike's VIN number engraved into the chasis.
Also every vehicle has a homologation card. In that card you will find same numbers.
At least that's how it is in my country, I am from European union.
Did you find any different in how the bike performed with the different dB killers ?
I have only been driving with the hard DB killer as I think the noise is load enough anyway. But with the hard DB killer I feel it has a little more power at low rev, but otherwise the same as the stock exhaust. There was one comment by Rhonwyn below who stated he felt it lost power without a DB killer inserted.

Thanks!
Nice sounding pipe! I run a Scorch pipe on my Yamaha tenere 660z , sounds quite similar! Does yours tend to backfire around 3000rpm if you flick the throttle or decelerate?
Because of the AIS system mine backfires during deceleration, but I have not experience any backfire at other conditions.
hej.Holder den max 90 db med medium db killer.er lidt itvivl om det er øvreste eller nedreste tal på måler der skal aflæses. mvh Preben
The App I use to measure the sound level is an iPhone app and only gives an indication of the level, although I have tried to measure the sound level as close as I could according to the official guidelines. I use the hard db killer myself as the hard db killer from what I can measure with the app should be legal. I am somewhat in doubt with the medium db killer. But as written it is only measured with an iPhone app (the highest number). You might have to go to an official authority measurement to be sure. The lowest number is an average over time, which I did not take into account.
Hey, Is that Round of Oval type of exhaust?
Hi, it is the round type.
Hi, I put this on mine xt too. where did you buy that small catalytic converter? Sound like it's less noisy with it.
I can't remember where I bought it and I can't find the invoice, sorry. But if you google "6522K" you should be able to find a place to buy the catalytic converter?
@@mcbluestreak5607 but it is quieter with cat then with hard db killer alone in real life?
@@andrewsoldan6050 There might be a small difference, but almost unnoticeable, as I recall. I installed the catalytic converter to make it legal in Denmark. And yes, the Dominator exhaust makes loader sound than the stock exhaust even with the hard db killer. I installed the Dominator exhaust primarily for weight loss compared to the original and found a little better torque at the bottom rpm with the hard db killer installed. And then I got used to the higher sound level, for good or worse.
@@mcbluestreak5607 thanks, you're right need to get use to. On the db meter is not a lot louder then stock but because is very different sound. sounds louder :)
Hi. I've just installed this dominator. And I see a flame from the exhaust. Is it normal?
That is normal with the Air Induction System (AIS) and the shorter pipes compared to the stock exhaust. Here is the text from the service manual: "The AIS burns unburned exhaust gases by injecting fresh air into the exhaust port....." etc. So this will happen typically when speeding down.
block the AIS pipe, runs better and no flames.
Hola! El silencioso es el redondo o el ovalado? Es que he pedido el redondo y he visto que montas los mismos soportes que yo, y estoy algo preocupado por si no me entran. Un saludo desde España! Y gracias!
It was the round exhaust I used. And thank you for commenting.
@@mcbluestreak5607 muchas gracias por responder!! Un saludo!!
hi, is that pipe very hot? I mean when you put panniers or bags is still ok? no melting?
Hi, I have not had any problem with a hot pipe. No melting of bags or anything despite it is very close (millimeter) to the rear fender. The distance from the pipe to my bags are around 3.5 cm and around 1 mm (millimeter) from the fender, so for me no problem.
@@mcbluestreak5607 thanks, maybe I get one too then. 5kg is good saving.
how was the fitment, all good? and was it not too loud at highway speeds?
The fitment is fairly good, but not perfect in my mind. It did require some fiddling. The noise is acceptable for me at highway speeds with the hard db-killer inserted. It is though a bit loader than the stock exhaust.
@@mcbluestreak5607 thanks, and what is the can length?
@@robsonenduro3316 I have the long one, of which the can is 41 cm plus 5 cm outlet nose and 2.5 cm connection. Total 48.5 cm.
@@mcbluestreak5607 thanks, I guess long one is quieter.
Hi, is this exhaust street legal, and if so, how did you homologate it?
At the time the video was made the exhaust did not have the EU approval (stamp on exhaust). What I did was to ensure it had the minimum noise level with the hard db killer and I installed a catalytic converter in the pipe. I never tried to get it approved, however, I think it might be possible to get it officially approved at least here in DK, but it does require a new inspection at a test center.
Det ska larme lidt (:
Har lige bestilt til min TLS. De skrev på ordren at DB killer var incl, men det må jeg vente og se om er korrekt. Ud fra dig er den ikk med ..
Som jeg husker det, fulgte der en type DB killer med efter eget valg, og så var den anden et tilkøb. Men det kan være at jeg husker galt.
Have a high sound than the original, its a great because its less weight, and simple, but the sound its than enduro bike.
That is also my impression even with the hard db killer in. Thanks.
Is it the dominator gp1?
No, it is the cheapest steel - marked "round" specific for Yamaha XT 660 Z
@@mcbluestreak5607 just after ordering it for my xf650 😎, some noise off it👍
@@gracecartel8855 Yes, I am using the hard db killer in mine.
@@mcbluestreak5607 ordered that also , nice purr out of it with the hard db
@@gracecartel8855 you mean the bike got even more quiet in comparison with your stock exhaust (incl.hard killers)?
Is it street legal?
It is not E-approved as there is no approval mark on the exhaust I got. But, from what I can measure with the db phone app, it should be below the legal noise level for a Yamaha XT660Z with the hard db-killer inserted. However, again this was measured with a phone app, so...?
Eeeeee..... eeeeeee.......eeeeeee.......eeeee.....
